Note 1:
AcroPack carriers without provisions for the isolated power supplies
can provide external power from the field power to the AcroPack module on
pins 48, 49 and 50.
ACROPACK MODULE INSTALLATION
Power should be removed from the carrier board when installing AcroPack
modules, cables, termination panels, and field wiring. Refer to Figure 2 while
reading this section. To install, first insert the edge of the AcroPack module
into the carrier connector at an angle similar to that shown in the figure. Next,
using a rocking motion while gently applying force to keep the edge of the
board against the back of the carrier connector, position the module such that
the field I/O connector is just above the mating connector. Verify that the two
connectors are properly aligned. Once alignment is achieved, you can fully
seat the connector. It will snap into place. Install two M2.5 screws as shown.

FIELD GROUNDING CONSIDERATIONS
The Field I/O signals are isolated from chassis and system ground on the
carrier. However, some AcroPack modules connect Field I/O ground to system
ground. Care should be taken in designing installations without isolation to
avoid ground loops and noise pickup. This is particularly important for analog
I/O applications when a high level of accuracy/resolution is needed (12-bits or
more). Contact your Acromag representative for information on our many
isolated signal conditioning products that could be used to interface to the
AcroPack input/output modules.
